ABB Bailey PHARPS32200000 F8-G2B9B3B6 MPS III Multi-Output Rack Power Supply Module

PHARPS32200000 with order code F8-G2B9B3B6 is ABB Bailey MPS III modular multi-channel power supply, dedicated to INFI 90 / Symphony Harmony DCS rack systems. It converts wide-range AC mains into five groups of isolated regulated DC power, providing stable power for controllers, analog/digital I/O boards, communication cards and field sensors inside the DCS cabinet, eliminating voltage fluctuation interference to guarantee uninterrupted process control operation.

This hot-swappable rack-mounted power unit adopts forced air cooling and full metal shielding housing, with built-in multi-layer hardware protection circuits. Original production has been discontinued, now it is a core aftermarket spare part for overhaul, replacement and backup of aging thermal power, petrochemical and papermaking Bailey INFI90 DCS control racks.

Core Functions

• Supply multi-group isolated stabilized DC power to all boards inside INFI90 DCS rack, meeting different power requirements of CPU, signal acquisition and communication modules separately.
• Full galvanic isolation between each output channel to suppress ground loop noise and electromagnetic interference from high-voltage field equipment, improving signal sampling accuracy.
• Complete hardware fault protection logic: automatically cut off abnormal output and trigger cabinet alarm when overload, short-circuit or overheating occurs to avoid batch damage to DCS control boards.
• Hot-swap support allows single power supply replacement without full DCS system shutdown, greatly shortening equipment maintenance downtime in continuous production factories.
• Built-in load balance and voltage compensation circuit, maintaining stable DC output voltage even under frequent dynamic load changes of process control systems.
• Standard Bailey rack unified mechanical and electrical definition, plug-and-play replacement without modifying cabinet wiring or adjusting system power parameters.

Application Scenarios

• Main rack power supply spare replacement for ABB Bailey INFI90 / Symphony Harmony DCS cabinets in thermal power plants and hydropower stations.
• Multi-output power backup spare parts for petrochemical refineries, natural gas stations and pulp & paper mill legacy distributed control systems.
• Maintenance inventory for metallurgical rolling mills, cement kilns and chemical fertilizer factory continuous process automation control rooms.
• Matching power unit cooperating with Bailey series CPU controllers, analog/digital I/O modules and redundant communication boards.
• Retrofit replacement components for aging DCS racks with unstable voltage, frequent board reset and power alarm faults.

• Global aftermarket spare stock for process industry maintenance workshops maintaining discontinued ABB Bailey DCS hardware.
